基于生物相容性的Ti/ZrO2接头钎焊工艺及连接机理研究

医用金属-生物陶瓷部件在生物医疗领域有着广泛应用，随着医疗器件可植入要求的日益提高，生物相容性成为这类部件应用的关键问题。本项目以生物相容性为切入点，针对可植入器件中钛合金和ZrO2生物陶瓷的钎焊连接，在钎料体系设计与优化、接头组织演化及连接机理、接头生物相容性影响因素及评价等方面展开系统研究，阐明“连接材料-钎焊工艺-接头组织-接头力学性能-接头生物相容性”的对应规律。本项目旨在开发具有生物相容性的连接体系，提出钎料体系设计准则和接头制备方法，建立接头生物相容性的影响控制路线图，实现钛合金和ZrO2生物陶瓷高质量连接，为获得优异生物相容性的医用金属-生物陶瓷封接部件提供新的思路。

Medical metal-bioceramic components are widely used in the biomedical field. With the increasing requirements for implantable medical devices, biocompatibility has become the key issue limiting the performance of such components. This project takes biocompatibility as the starting point and focuses on the brazing of titanium alloy and ZrO2 bioceramic in implantable devices. Systematic researches emphasizing on the design and optimization of intermediate layer, joint structure evolution and joint mechanism, and factors affecting joint biocompatibility will be conducted to clarify the relationship of "joining material - brazing process - joint structure - joint performance - joint biocompatibility". The project aims to develop a biocompatible joining system, propose intermediate layer design guidelines and joint preparation methods, establish a control roadmap for joint biocompatibility, and achieve high quality connection between titanium alloy and ZrO2 bioceramic with reliable performance, shedding lights on the manufacture biocompatible medical metal-bioceramic hybrid components.
